Anti-hardening acid-corrosion-resistant fluffy biological deodorization composite filler

Abstract

The invention provides an anti-hardening and acid-corrosion-resistant fluffy biological deodorization composite filler, which is characterized by comprising the following components in percentage by volume: 70-80% of original ecological bamboo charcoal; 1%-2% of plastic hollow sphere / Pall ring; 8%-12% of pine barks, pine scales and / or coconut shell blocks; 2%-3% of light biological ceramsite; and 9%-13% of oyster shell / oyster shell. The composite filler is suitable for attached growth of deodorization microorganisms, raw materials are easy to obtain, wide in source, high in porosity and void ratio, light in weight, small in air resistance, large in biological loading capacity, resistant to microbial acid corrosion and capable of neutralizing acid production, and collapse is reduced after long-term operation; and the deodorization efficiency is high, the service life is long, supplementation is easy in the later period, the autonomy of a user is high, carbon is low, energy is saved, the use cost is low, and the cost performance is high.

Description

technical field [0001] The invention belongs to the technical field of deodorizing fillers, in particular to the technical field of fillers for malodorous gas microbial deodorization filters / towers, in particular to an anti-hardening and acid-corrosion-resistant fluffy biological deodorization composite filler. Background technique [0002] Odor pollutants refer to gaseous substances that stimulate the sense of smell, cause unpleasantness and damage the living environment. Odor pollution is widely distributed and has a wide range of influence, for example, in sewage lifting pump stations, grill rooms, aerated grit chambers, primary sedimentation tanks, anaerobic biochemical tanks, etc. in the process of sewage treatment; in the process of sludge treatment Sludge concentration, dehydration and drying, transfer and other links; in the process of composting, sanitary landfill, high-temperature incineration, cleaning and transportation, etc. in the process of garbage treatment; ...

AI Technical Summary

Problems solved by technology

The second layer and the first layer are stacked up and down. After the filler is filled with fine particles such as fly ash and wood chips, it will become dense with time due to gravity, so the air resistance loss will increase. The fan used is a two-stage fan, and Not resistant to the chemical corrosion of deodorizing microorganisms producing acid, because the activated carbon on the first layer is easy to absorb and saturate, it is difficult for microorganisms to regenerate the activated carbon under dry operation conditions, and the odorous substances are intercepted and adsorbed during non-wet operation Poor capacity (anhydrous film dissolves and absorbs), therefore, this complex device has high energy consumption but general deodorization efficiency, so the filler and method have their limitations

The surface nanospace of the filler is easily filled and blocked by microbial residues, so that the actual specific surface area is limited, and the amount of microorganisms that can grow on the filler is insufficient. In addition, the wind resistance of the volcanic rock and stone rice pile is large, and the energy consumption of the filler layer is high. The deodorizing effect is difficult to meet the high standard requirements
